Definitions

  • the present invention structure and procedure for assembling concrete used in wind turbines refers to an original and innovative structure and its associated assembly procedure, for the construction of wind turbine generators in wind farms.
  • the present invention will be of particular interest for the industry supplying wind turbines for making use of wind energy and for the construction industry in respect of civil work for this type of installation.
  • utility model U200502266 "Mould perfected for the execution of prefabricated concrete elements for the construction of modular towers for wind turbines" is an invention consisting of formwork made from metal, PVC, fibreglass or any other material, required to manufacture elements with complicated geometry and strict tolerances, required in the manufacture of towers within the same scope of application as the present invention.
  • This invention satisfactorily resolves specific problems associated with manufacture, using precast concrete, of elements for the construction of modular towers for wind turbines.
  • Utility model U200501400 Perfected structure of joints between plates of modular towers for wind turbines and other applications consists of an innovative and original structure for joining the plates which make up the aforementioned towers, supporting the wind turbine electricity generators.
  • the structure and assembly procedure for the wind turbine concrete towers which is the object of this invention and which is described below, consists of a procedure for erecting the concrete towers consisting of various stages or phases, as defined by claim 1, which may be developed at the same time in the different towers of a wind farm, including erection and pre-assembly activities of the sections of each tower of a wind generator in which each section of the tower structure may be composed of a different number of segments or longitudinal sections depending on the situation of that section in the height of the tower.
  • This process comprises two differentiated sequences, one of pre-assembly for each tower section and the erection of said sections, including a pre-assembly phase for each section, a process divided into the following stages, for each section comprising different segments: a phase for the transport and erection of each segment, therefore there being as many phases as there are segments, followed by a final phase comprising filling in of the vertical joints of each section.
  • the aforementioned pre-assembly cycle is carried out for the first section of the wind turbine tower directly on the final site on the base footing or foundation of the turbine whereas the other intermediate section are pre-mounted on assembly bases which are placed on the ground on the platform area provided in the proximity of the base of each wind turbine or on the base itself, placing the segments in their position with the aid of stabilising and bracing struts.
  • the erection cycle is begun following the first pre-assembly cycle, in the same wind turbine and this consists of placing each section on the previous one by hoisting with the aid of a crane and fitting it into the connection system of each section.
  • the Pre-assembly cycle of the first section also includes the following stages as a minimum, in the case of a tower consisting of four segments:
  • the Pre-assembly cycle of the intermediate sections includes at least the following stages in the case where there are three segments.
  • the horizontal joints shall include at least the following stages:
  • the procedure for erecting concrete towers used in wind turbines illustrated in this preferential form of realisation consists basically of various stages or phases which may be developed at the same time on a parallel basis with the various towers in a wind farm, thus making optimum logistical use of the resources, materials and times necessary for assembly.
  • the aforementioned procedure includes two different cycles of activity which may be developed alongside each other: the pre-assembly cycle and the erection cycle.
  • both cycles have the same productive capacity: two towers per week.
  • the pre-assembly cycle begins its activities some weeks beforehand, so that there is always a minimum advantage of having various towers in the erection cycle, thus avoiding interference of one over another.
  • Each section (4) of the tower structure may be composed of different number of segments (1) based on their position in the height of the tower.
  • the first section (0-20) corresponding to the first twenty metres of height of the tower is made up of four segments, each limited by vertical sections (8) of that section of tower.
  • the second section (20-40) between twenty and forty metres of the tower height is composed of three segments, as well as the third section (40-60) that is, at a height of forty to sixty metres of the tower height which is also composed of three segments.
  • the fourth section (60-80) comprises two segments which come already pre-assembled in the factory in one single part.
  • the aforementioned pre-assembly for each section consists of a procedure divided into the following phases, for each section comprising different segments: one phase for transport and erection of each segment, therefore there are as many phases as there are number of segments, followed by a final filling stage of the vertical joints (8) of each section.
  • the pre-assembly of the first section (0-20) will be carried out in six stages, one comprising the arrival and assembly of each of the four segments, a fifth phase for filling the horizontal joint with the base footing and a sixth phase of filling the vertical joints, whereas the two following sections (20-40) and (40-60) shall be erected in four phases each, three for the arrival and erection of each segment and a fourth for filling the vertical joints.
  • the pre-assembly of the first section can be directly carried out on the base footing or foundation of the wind turbine, while the other intermediate sections shall be erected on mounting bases (5), which may be placed on the ground in the zone of the platforms provided in the proximity of the base of each wind turbine, or on the base itself in a position next to the tower.
  • the aforementioned cycle of erection is initiated following the first pre-assembly cycle in the same wind turbine, and consists of the placing of each section on the previous one; in this case, the placing of three sections each 20 metres high. In this operation each section is hoisted with the aid of a crane.
  • the pre-assembly cycle is begun with erection of the segments of the first section of the present structure of each concrete tower for wind turbines, which in this preferential form of realisation comprise the 20 first metres of the tower.
  • the structure of the aforementioned first section comprises four segments (1) in the form of a section of the trunk of a straight or curved generator cone provided with hoisting bolts (10) enabling them to be mounted directly onto the definitive foundation.
  • the pre-assembly of the first section of each tower comprises the following stages:
